So, I'm playing with decorators in Python 2.6, and I'm having some trouble getting them to work. Here is my class file:
class testDec:
    @property
    def x(self): 
        print 'called getter'
        return self._x
    @x.setter
    def x(self, value): 
        print 'called setter'
        self._x = value
What I thought this meant is to treat x like a property, but call these functions on get and set. So, I fired up IDLE and checked it:
>>> from testDec import testDec
from testDec import testDec
>>> t = testDec()
t = testDec()
>>> t.x
t.x
called getter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "testDec.py", line 18, in x
    return self._x
AttributeError: testDec instance has no attribute '_x'
>>> t.x = 5
t.x = 5
>>> t.x
t.x
5
Clearly the first call works as expected, since I call the getter, and there is no default value, and it fails. OK, good, I understand. However, the call to assign t.x = 5 seems to create a new property x, and now the getter doesn't work!
What am I missing?
